To @ZZ whom t may concern:

Be it known that I, ALEXANDER W. OOP- LAND, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Depositing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings. v

The invention relates to new and usefulimprovements in depositing-machines; and it consists in the construction particularly of the means for receiving the dough from the hopper and depositing it, and, further, in the construction, arrangement, and combination of the various parts, as more fully hereinafter described, and particularly pointed out in the claims. y

In the drawings, Figures 1 and 2 are side elevations of opposite sides of my machine. Fig. 3 is a vertical section through the hop- Fig. 4 is a similar Vsection showing the segmental piston in a different position. Fig. 5 is a vertical central section on line of Fig. 3. Figs. Gand 7 are perspective views of the piston and abutment-block. A is the framework which supports the operating parts, having amain drive-shaft B,

driven from any suitable source of power.` -O is a tilting table pivoted near one end on the shaft C and at its other end supported on each side by links D, supported on the levers E, keyed on the shaft E and operated by a suitable cam on the shaft B, so that the table 4can be raised and lowered the desired amount. On the table C is a carrier F. This carrier passes over the rollers a and o at opposite ends of the table. The carrier is fed forward by means of the pawl con the lever d, which is connected by the link e to the upper end of the lever f, which is moved in one direction by the spring f and in the other direction by a suitable cam on the shaft B, bearing on a roller f on the lever f, these parts being no part of my presentpinvention, and I do not deem lit necessary to further describe them.

G is a hopper provided with a lateral exitport G at the bottom. The base H of the hopper is provided with a slot I. In place of the slot I may make a series of separated ports, if desired; but for convenience in cleaning I prefer the single slot. Below the slot or port I is detachably secured a nozzle-plate J,V having a slot or a series of discharge-openings t therethrough, and preferably having a nozzle around each opening, as shown. 1n the wall K and in the base of the hopper adjacent to the discharge-port G' are formed bearings in which is journaled the cylinder L. This cylinder extends at `its ends into the cylindrical extensions r1 o, formed at the base of the hopper. The extension t" has an enlargement j, into which the cylinder also extends. In this enlargement and secured to the cylinder is the gear il'. Z is an end plate, having the central extension m projecting into the cylinder. This end plate is bolted or otherwise secured to the enlargement j of the hopper, so as to prevent it from rotation'. The projection m is provided with a squared bearing n, in which engages an extension 0 on the end of the stationary segmental abutment-block o', which extends through the cylinder. At the other end the block is provided with an extension p, engaging a suitable bearing in a sleeve p,tting within the cylinder and secured to the extension z'. Extending centrally through the cylinder is a shaft q,to which is secu red the segmental piston r. This shaft is journaled in bearings in the extension m at the connecting-rod M' with the eccentric M"l on the shaft B. Suitable means (which it is notl necessary to describe) are provided for adjusting the length of the crank-arm M and for adjusting the length of the connecting-rod M.

By this connection the segmental piston l7' is rocked yto draw in the material from the hopper and to discharge it through the dischargeport. 'lhe cylinder is given a partial rotation, so as to register its discharge-port u with the port G of the hopper or with the exitports by means of the rack-bar N, which meshes with the gear k. The enlargementq' is cut away on one side to allow this gear c to project therethrough, so that the rack may engage therewith, as shown in Fig. 2. This rack is guided in a suitable guide N on the side of the hopper, and is connected to the bar N", which is provided with roller-wrists O and O' at opposite sides of the cam P. The bar N hasia slot P', which embraces the shaft B, so as to guide it in its movement. This cam is so constructed as to give the desired movement to the rack-bar N, and through the gear c to partially rotate the cylinder for the purpose 4previously described.

`The `parts being thus constructed their op- .eration is as yfollows: The material being placed in the hopper G the cylinder L is irst lrocked, so that this port a connects the interior of the cylinder with the hopper. T he segmental piston#q is then moved from lts lowermost position to its'upper position and draws the material from the hopper into the cylinder. to the`position shown in Fig. 3, registering the port u with the discharge-ports through the nozzle, and the piston 7' is then rocked downward, forcing the material ont. The

table having suitable pans on it carried by the endless.- carrier is then fed downward and -forwardin position for another deposit.

This construction is exceedingly simple both in its'construction and the number ofparts employed. Itcan be readily cleaned, and all the ports and passages are large and clear, so

`that it will reduce the amount of friction,

kneading, or churning in the operation of the device.

What l claim as my invention is- 1. The' combination of a material-hopper having an exit throat or port, a cylinder journaled in said throat having a port, a dischargepassage below the throat, a stationary abutment in the cylinder, a rocking piston in. the cyllnder, and means for rocking the cylinder and pistonv'for the purpose described.'

2. The combination of a material-hopper having'an apertured base, and an exit-throat above the'aperture inthe base, of a cylinder journaled in said throat having a port in its side adapted to be registered with the hopper or the aperture in the'base, a stationary abut- The cylinderisthen rocked back i eenen ment in the cylinder, a rocking segmental piston in the cylinder, and means for rocking the cylinder scribed.

3. The combination of the material-hopper having a discharge-throat, a discharge-port below the throat, a cylinderjournaled in said and piston, for the purpose de- 40 throat and having a port adapted to be regl-v istered with said hopper or the dischargethroat, amextension of the cylinder outside the hopper, a gear thereon, a rack and vmeans for reciprocating the rack to rock the cylinder.'

v 4. The combination of the material-opper having a discharge-throat, a ported cylinder .journaled therein, and extensions at the base of thehopper in which the ends of said cylinder rotate, the enlargement of one of -said the shaft, and the detachable abutment in the cylinder. p I

In testimony whereof I ailx my signature in Vpresence of two witnesses.
